Rolltronics

Rolltronics is a corporation that is using a new approach in electronic manufacturing, producing electronic devices on flexible substrates using roll-to-roll manufacturing techniques.

Because Rolltronics is interested in producing electronic devices on flexible substrates, OLEDs seems to be a focus at there company. For this reason, Rolltronics web site contains some great articles about OLEDs.

I have listed the articles below:

• Introduction to Organic Light-Emitting Diodes (OLEDs)
• OLED-Based Displays

Microdisplays, miniature high-resolution displays viewed through magnifying optics, are about to produce a revolution in the capability of hand-held or wearable portable devices. Although today's hand-held devices are limited to a relatively few lines of text on a several-inch diagonal screen, microdisplays can offer a virtual image equivalent to that of a 14- to 19-inch computer monitor or a wide-screen TV. Tomorrow's high-performance, virtual imaging modules will provide access to information-rich text, data and video, which can facilitate the opening of new mass markets for wearable PCs, wireless Internet appliances and mobile phones, portable DVD-viewers, digital cameras, and other emerging applications.

A primary enabler of this new generation of displays is CMOS silicon technology, which permits an extraordinary amount of electronic complexity to be packaged on a small chip of silicon. With the proper display design, this complexity can be used to control the elements of an image display, forming what is known as an active matrix display. A new microdisplay technology, organic light emitting diodes (OLEDs), has emerged as nearly ideal transducers for use with silicon active matrix chips. The OLEDs are easily formed from evaporated thin films laid down on top of the silicon, the required voltages are low enough to allow the use of inexpensive silicon processes, and the optical characteristics are well-suited for use with magnifiers. They are efficient, resulting in low power consumption, and the fact that they emit light rather than modulate transmitted or reflected light results in viewing modules that are smaller and lighter. The integration of OLEDs with integrated circuits permits many computer and video electronic system functions to be built directly on the silicon IC under the OLED layer, resulting in an ultra-compact system with lower overall system costs relative to alternate near-eye display technologies.
